DUMP-CAR.

Specification of Letters Patent.

Patented Nov. 1, 1910.

Application filed March 11, 1910. Serial No. 548,517.

To all whom it may concern:

Be it known that I, ARGYLE CAMPBELL, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented a new and useful Iniprovement in Dump-Cars, of which the folploy to practically accomplish this object or result as herein shown and described and more'particularly specified in the claims.

In the accompanying drawing forming a part of this specification, Figure 1 is a plan view showing one-half or end of a dump car embodying my invention. Fig. 2 is a side elevation. Fig.3 is a, vertical cross section. Figs. 4, 5, 6, 7 and 8 are detail views of the door operating mechanism. Fi 9 is a side elevation, illustrating as a mo ification the application of my invention to a fiat bottom gondola. car. Fig. 10 is a cross section on line 10-10 and 10"-10 of Fig. 9 and Fig. 11 is a detail elevation showinga ortion shaft t ereon. Fig. 12 is a cross section on line 12-12 of Fig. 13 and Fig. 13 is a detail plan view, of the mechanism shown in Fig. 11.

In the drawing, 1 represents a dump car,-

2 the wheels thereof, 3 the center sills, 4 the upright sides of the car body, 5 the floor or bottom, the same bein preferably inclined or hop )er sha ed at the ends, 6 the longitudina centra hopper sheetextending over the center sills, 7 transverse hopper sheets extending across the car between the door openings 8, on each side of the central hopper sheet and 10 are longitudinallyhinged doors closing the door openings on each side of the central hopper sheet and between the transverse hopper sheets. The several side dump doors 10 on each side of the longitudinal hop er sheet are hinged at their upper outer ges to the upright sides of the car body by hinges 11. And the several doors 10 on each side of the central hopper sheet dered lockin face, flexible connecting nectin'g two adjacent are connected together by acommon movable operatmg shaft 12, journaled insuitable bearings 13, attached to the doors 10 near their lower or free edges. llach of the movable operating shafts 12 is furnished with a plurality of polygonal drums 14, each preferably four sided and havin a locking face or side 15 furnished with a s oulder or proection 16. Each of the drums 14 also has a pivot'lug l7 and guides or flan es 18 on the side thereof opposite the pivot u A plurality of links 19, 20, 21, preferabIy three in number, connect the drum of the operating shaft with the transverse hop or sheet 7 at 23. One of the connecting lin rs, preferably the middle one, 20, has on its inner face a locking shoulder 24 adapted to interlock with and en age the locking shoulder on the face of the drum. The movable door operating shaft 12 is connected with and operated from the fixed winding shaft 25 journaled on the car body by a winding chain 26 which engages a chain winding drum 27 on the operatin shaft 12.

In the mo ifica-tion shown in Fi s. 9 to 13, the construction is the same wit ception that the invention is illustrated as being applied to a gondola or flat bottom car, instead of to a hopper bottom car.
